Hamilton | March 17, 1998 |
A quick disconnect nozzle comprising a nozzle body, a spray tip, and an annular sealing member interposed therebetween. The tip is adapted to be inserted axially into the body and then rotated. When the tip is rotated, camming lugs on the tip and body coact to draw the tip axially toward the body and compress the sealing member. Detents in the form of flexible curved ribs are carried by the tip and resiliently pop into curved pockets in the body to releasably hold the tip in its installed position. The sealing member is an O-ring which is carried by the tip and which is removable from the body as a unit with the tip. An inner seal is provided between mutually converging tapered walls of the nozzle tip and nozzle body adjacent the inner end portion of the nozzle tip.
